4.2.1 Command Line Options

To configure a QSP-200/300 in the system, the Enabler requires one command line argument from the user to determine the configuration of the card. This argument must be enclosed in parenthesis and within the argument, any or all of the following parameters may be specified using a comma (no spaces) to separate each parameter:

Ssocket

specifies which PCMCIA socket the QSP-200/300 must be inserted into for this

 

configuration argument to be used. socket must be in the range 0 - 15. This option is

 

always required.

 

 

Baddress

specifies the base I/O address of the QSP-200/300 in hexadecimal and must reside

 

on an even 32-byte (20H) boundary. This option is required if the 'R' option is not

 

used.

 

 

Iirq

specifies the interrupt level (IRQ) of the QSP-200/300 in decimal. irq must be one

 

of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is desired.

 

This option is required if the 'R' option is not used.

Waddress

specifies the base address of the memory window required to configure the

 

QSP-200/300. Set address = D0 for a memory window at segment D000, address =

 

D8 for a memory window at segment D800, etc. Valid settings for address are C8,

 

CC, D0, D4, D8, and DC. If this option is omitted, a memory window at segment

 

D000 will be used.

 

 

Omode

specifies RS-422/485 output driver mode. The QSP-200/300’s ports may be

 

configured for either full duplex or half duplex operation with this option. If this

 

option is omitted, the default setting is the RS-422/485 ports are configured for full

 

duplex operation with the RS-422/485 output drivers always enabled. In half duplex

 

mode, the RS-422/485 transmitter may be enabled and disabled via the RTS (request

 

to send) or DTR (data terminal ready) signals. Both RTS and DTR are controlled

 

through the Modem Control Register of the 16550. See the Hardware Information

 

section for more information.

Hinstructs the Enabler to enable the RTS-CTS modem control handshake. When modem control handshaking in enabled, the 16C550 UART’s RTS and CTS signals are connected to the RS-422/485 auxiliary channel (AuxOut and AuxIn). The auxiliary channel may then be used for handshaking between a QSP-200/300 RS-422/485 port and a peripheral device. When modem control handshaking is disabled, the RTS and CTS signals from the 16C550 UART are looped back to each
